Final answer:
It is true that employees with exposure to bloodborne pathogens must receive initial and ongoing training on handling these hazards, with the frequency of training often being annual.
Step-by-step explanation:
It is true that all employees with occupational exposure to bloodborne pathogens must receive initial training on how to handle these hazards properly. Moreover, they are required to undergo follow-on or additional training at regular intervals. The exact frequency of this training may depend on regulations specific to the country or state they are working in, however, the Occupational Safety and Health Administration (OSHA) in the United States typically mandates annual training updates.
For example, health-care workers who are potentially exposed to bloodborne pathogens, such as HBV (Hepatitis B virus), must take specific precautions to prevent infection. These precautions include wearing protective clothing, using proper disposal methods for needles and other sharp objects, and using a 10% bleach solution to disinfect contaminated surfaces.
When working in a laboratory setting, particularly with BSL-2 (Biosafety Level 2) bacteria, additional safety practices must be employed, such as using biohazard warning signage, wearing protective clothing, and ensuring proper disposal of bacterial cultures.
